NiPSysGrowFadeModifier
From GECK
NiPSysGrowFadeModifier is a modifier for particle systems that grows and shrinks particles based on their generation and lifespan. Particle size is on a 0 to 1 float range, with zero being completely shrunken and one being full size.
Its fields are:
- Name: The name of the modifier.
- Order: 3000 seems to be the only one used, it's a "general modifier" flag.
- Target: The particle system you wish to affect.
- Active: If the modifier is enabled. You can animate this value by specifying the name of the modifier as the Controller ID in a NiControllerSequence and using a NiPSysModifierActiveCtlr as a controller with a NiBoolTimelineInterpolator as the interpolator.
- Grow Time: Grows particles from the base scale value to full size over this period (in seconds?)
- Grow Generation: Only particles of this generation will grow. Set to 0 to have every particle grow.
- Fade Time: Shrinks particles from the base scale value over this period (in seconds?)
- Fade Generation: Only particles of this generation will shrink. Set to 0 to have every particle shrink.
- Base Scale: Marks the minimum size of particles when handled by this modifier. Added by Bethesda.
